The effect of
reducing the evaporator pressure on a simple vapour compression refrigeration
cycle is:
एक साधारण वाष्प संपीड़न प्रशीतन चक्र पर बाष्पीकरणकर्ता दबाव को कम करने का प्रभाव है:
The
temperature in condenser is increased
There is a
reduction in the refrigerating effect
The expansion deviates from isenthalpic
Compression
work required is reduced
There is a
reduction in the refrigerating effect
●There is a
reduction in the refrigeration effect due to reducing the evaporator pressure
on a simple vapour compression refrigeration cycle.
●Both
evaporator and condenser pressures should be positive. If the pressure is lower
than atmosphere, there is possibility of leakage of air, the presence of non-
condensable gas in side system causes drastic decrease in capacity of
refrigeration system.
Hence, the correct option is (B).
&Key Points:-
Lower
evaporating temperature/pressure reduces COP of the system. Therefore, it can
be concluded that lower suction pressure/temperature is not desirable for the
refrigeration system.
